BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begoniaplant, botanically known as Begonia boliviensis, and hereinafterreferred to by the name ‘Dobegicposunris’.

The new Begonia plant is a product of a planned breeding programconducted by the Inventor in De Lier, The Netherlands. The objective ofthe breeding program was to develop new freely branching and floweringBegonia plants with unique and attractive flower colors and tolerance tohigh temperatures.

The new Begonia plant originated from a cross-pollination made by theInventor during the autumn of 2014 of a selection of Begonia boliviensisidentified as code designation BG13-0000506-001, not patented, as thefemale, or seed, parent with a selection of Begonia boliviensisidentified as code designation BG13-0000594-001, not patented, as themale, or pollen, parent. The new Begonia plant was discovered andselected by the Inventor as a single flowering plant from within theprogeny of the stated cross-pollination in a controlled greenhouseenvironment in De Lier, The Netherlands during the spring of 2015.

Asexual reproduction of the new Begonia plant by vegetative tip cuttingsin a controlled greenhouse environment in De Lier, The Netherlands sincethe spring of 2015 has shown that the unique features of this newBegonia plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environment such astemperature and light intensity, without, however, any variance ingenotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Dobegicposunris’. Thesecharacteristics in combination distinguish ‘Dobegicposunris’ as a newand distinct Begonia plant:

-   -   1. Relatively compact, upright to spreading and mounded plant        habit.    -   2. Moderately vigorous growth habit.    -   3. Freely basal branching habit.    -   4. Dark greyed green-colored leaves.    -   5. Freely and continuously flowering habit.    -   6. Large double and single flowers that are dark yellow and        orange red in color.

Plants of the new Begonia can be compared to plants of the parentselections. In side-by-side comparisons, plants of the new Begoniadiffer primarily from plants of the parent selections in growth habit asplants of the new Begonia are more uniform than plants of the parentselections.

Plants of the new Begonia can be compared to plants of the Begoniaboliviensis ‘Dobegicpocit’, disclosed in a U.S. Plant patent applicationSer. No. 16/501,714. In side-by-side comparisons, plants of the newBegonia differ primarily from plants of ‘Dobegicpocit’ in flower coloras plants of the new Begonia have dark yellow and orange red-coloredflowers whereas plants of ‘Dobegicpocit’ have light yellow-coloredflowers.

Plants of the new Begonia can be compared to plants of the Begoniaboliviensis ‘Dobegicpocor’, disclosed in a U.S. Plant patent applicationSer. No. 16/501,715. In side-by-side comparisons, plants of the newBegonia differ primarily from plants of ‘Dobegicpocor’ in flower coloras plants of the new Begonia have dark yellow and orange red-coloredflowers whereas plants of ‘Dobegicpocor’ have red-colored flowers.

Plants of the new Begonia can be compared to plants of the Begoniaboliviensis ‘Dobegicpororan’, disclosed in a U.S. Plant patentapplication Ser. No. 16/501,716. In side-by-side comparisons, plants ofthe new Begonia differ primarily from plants of ‘Dobegicpororan’ inflower color as plants of the new Begonia have dark yellow and orangered-colored flowers whereas plants of ‘Dobegicpororan’ have darkorange-colored flowers.

Plants of the new Begonia can be compared to plants of the Begoniaboliviensis ‘Dobegicposalm’, disclosed in a U.S. Plant patentapplication Ser. No. 16/501,717. In side-by-side comparisons, plants ofthe new Begonia differ primarily from plants of ‘Dobegicposalm’ inflower color as plants of the new Begonia have dark yellow and orangered-colored flowers whereas plants of ‘Dobegicposalm’ have light red-colored flowers.

Plants of the new Begonia can also be compared to plants of Begoniaboliviensis ‘Beauvilia White’, not patented. In side-by-sidecomparisons, plants of the new Begonia differ primarily from plants of‘Beauvilia White’ in the following characteristics:

-   -   1. Plants of the new Begonia have larger leaves than plants of        ‘Beauvilia White’.    -   2. Plants of the new Begonia have larger flowers than plants of        ‘Beauvilia White’.    -   3. Flowers of plants of the new Begonia face more upright and        outwardly than and not as downward as flowers of plants of        ‘Beauvilia White’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Begonia plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Begonia plant.

The photograph is a side perspective view of a typical flowering plantof ‘Dobegicposunris’ grown in a container.
